Description
These devices are designed to limit overvoltages between a system
and the protective ground. The TISP4700F3 is designed for insulation

SD4XAA
protection of systems such as LANs, and allows a float voltage of
500 V without clipping. IEC 60950 and UL 1950 have certain require-
Terminals T and R correspond to the
alternative line designators of A and B
ments for incoming lines of telephone network voltage (TNV). Any pro-
tector from the line to ground must have a voltage rating of 1.6 times the equipment rated voltage. International and European equip-
ment usually have maximum rated voltages of 230 V rms, 240 V rms or 250 V rms. Multiplying the 250 V value by 1.6 gives a protector
V_DRM value of 400 V. Allowing for operation down to 0 °C gives a V_DRM value of 420 V at 25 °C. This need is met by the TISP4600F3.
The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping
until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state
causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current prevents
d.c. latchup as the diverted current subsides. A single device provides 2-point protection. Combinations of devices can be used for multi-
point protection (e.g. 3-point protection between Ring, Tip and Ground).
The TISP4x00F3 is guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. This protection
device is in a DO-92 (LM) cylindrical plastic package.
